I have a 2 bedroom condo at the California Vacation Club at Indian Palms in Indio just a mile form the festival grounds! The condo will sleep up to six and is available for the week of 4/17--4/24. Rate for the week would be $825. Sorry not available on a "nightly" basis.
You can see more info on the property at http://www.indianpalmsvacationclub.com/
